rlhis invention relates to shields for radiators or other' devices from which convection currents arise and it has for its object the provision of a device of the class described adapt- 5 ed to fit over radiators of different length and having means adapted to block or substantially close the space between the radiator and wall, adjustable to fit spaces of various widths.

Otherv objects of the invention will appear as the following description of a preferred embodiment of the invention proceeds.

w Fig. 1 is a perspective view of the invention. i Fig. 2 is a cross section taken along the line 2-2 of Fig. 1 showing the invention applied to a radiator and in contact with an 'zu adjacent wall.

Before discussing in detail the several figures it may be stated that a common objection to radiators as at present installed is that the current of heated air rising between the ,radiator and adjacent wall carries with it dust from the floor which is deposited on the surface of the wall above the radiator or on window curtains or on the ceiling above. Furthermore it is known that where the current of heated air rises vertically above the radiator, there isl poor distribution of heat4 'within the room since the heated air accumulates near the ceiling, without mixing readily with the bulk of the air Within the room.

It is already known to provide radiators with defiecting shields for' throwing` the heated air current toward the center of the room and it is also known to close the space. be-

40 vent or reduce the passage of the air current 4'tween the radiator and the wall so as to pre-v simplified, and the work of installing the same facilitated. 1

The radiator shield of the present invention as shown, comprises a pair of cooperating telescoping sections l and 2. These sec- 'tions are preferably each formed like an inverted trough with front flanges 3 and 4 and rear flanges 5 and 6. The front and v rear flanges enable the shield or deflector to be fitted upon the top of the radiator without risk of its falling off while, since the sections are telescoping they may be pushed together or drawn out in order properly to fit the vradiator to which they are applied. The

vfront and rear flanges of the section 4 are bent over as shown at 7 and 8 to form channels or tracks in which the edges of the sece .tion l slide, the latter being thus retained by the former section. The two sections are provided with end flanges 9 and 10.

The front flanges 3 and 4 are preferably provided with series of perforations l1 and l2 the main object of which is toafford an escape for the heated air, into the room. The slots also perform the function of assisting in holdingthe' two sections together, any suitable boltingl means 15 being passed through any two slots which may be in registry when the shield or deflector is at its proper length.

One of the striking features of the invention is the means utilized to furnish an adjustment in connection with the rear flap or flange for permitting it to be accommodated to any width of space between wall and radiator which it may be desired to close. This adjusting means consists of a longitudinal linear weakened region 14 such as a score mark formed on the rear flap'; Along this mark or weakened region the lower portion of the flap may be hingedly bent backwards a suitable distance to form a closure for the said space, the angle of the flap being determined to suit the width of the space.

The score marks along the two sections are in line with one another-so that the telescoping of the sections by which their length is determined also determines the length ofthe angularly bent portion of the aps.

It is to be understood that in the present illustrative embodiment of the vinvention. the structure has been reduced to its ele- `mental form, but that in practice the invention may be carried out equally well in more ornate and complicated forms of shield or deiector.

It is likewise to be understood that the nventionis not confined to use .with heating radiators but that it is applicable to any device from which convection currents, hot or cold, maylemanate. A

While I have described what I believe to be a preferred form of the invention it is to be understood that numerous variations in the constructional details may be resorted to without transcending the invention provided that they can beconstrued to be within the terms of the appended claims.

What I claim is:

1. A shield for radiators adapted to fit over the top of a radiator, comprising cooperating telescoping sections, each in the form of an inverted channel and each having a front flange and a back flange, a iiap depending from the back flange to close the space between the radiator and an adjacent wall, the front flange and the flap of one section having turned edges in which the edges of the other section slide, said flap being adjustable by bending to it the said space between the radiator and wall, said front flanges being each formed with a series of apertures, the apertures of one series registering with those of another series when said sections'are in positions of adjustment.`

2. A shield for radiators adapted to fit over the top of a radiator and to close the space between the radiator and an adjacent wall,co1n

of an vinverted channel and each having a front flange and a backflange, a ap depending from the back ilange to close the space between the radiator and an adjacent Wall, the front flange and the flap of one section havin 1 turned edges in which the edges of the other section slide, said flap being adjustable by bending to fit the said space between the radiatorand wall, and said front flanges each having a series of air outletapertures,
